Title: Welding polyalkylene/polyamide laminates
IPC: B65D75/26
Filed: 1971-05-14
Abstract: In a process for welding laminates with several layers formed into bags and filled with highly viscous or plaste-like materials contg. organic solvents, the material placed in direct contact with the filling material is a sheet of polyalkylene and the sheet next to it is a sheet of polyamide.

Patent DE-2166191-A1 (DE)
Title: Catalytic exhaust gas afterburner - divided into several sections with the smallest preheated alone during cold start
Inventor: BRESSER WALTER
IPC: F01N13/04
Filed: 1971-02-02
Abstract: A catalytic afterburner for the exhaust gases of internal combustion engines is divided into a smaller and a bigger catalytic section, with separate inlets but a common manifold at the outlet. During the starting period, a flap valve keeps the inlet to the larger section closed. The smaller section quickly reaches its working temperature, and then the larger section via the common manifold, before the flap valve opens the access to both inlets. This utilizes the catalytic volume better than when a small unit is used just for starting and is then cut off. Purified exhaust gases are emitted very shortly after every cold start.

Title: Changeable indicator board - is rotatable to given angle by step drive and pair of gears
Inventor: WEISSKOPF ERNST
IPC: G08G1/09
Filed: 1973-09-26
Abstract: Changeable indicator arrangement comprises several prismatic indicator-shield-drums which are coupled by means of a tracking bar to a step adjusting turning mechanism through a given angle in the form of a maltese drive but which has a pair of tooth wheels for more sensitive control. A rotation of 90 deg. of the Maltese cross produces the usual change of direction of 45 deg. of the tracking bar. A coupling with an eccentric drive is not necessary since the bar does not emerge from its plane upon turning. However, it is easy to mount the indicator board on its own carriage or a square roller.

Patent DE-2410323-A1 (DE)
Inventor: GOERLICH LOTHAR
IPC: C02F3/28
Filed: 1974-03-05
Abstract: The raw sludge, for heating to pasteurisation temperature, is continuously transported through a heat exchanger and then delivered into one of three holding chambers, in which the pasteurisation is carried out batchwise. At the same time, pasteurised sludge from another of the chambers is continuously conducted away through a heat exchanger. In this heat exchanger, cooling is carried out after the pasteurisation in counter-current with the circulated heating medium serving for the heating in the first-mentioned heat exchanger. By means of the process, pasteurisation is possible in an energy-saving manner with particularly low expenditure in terms of apparatus. Working under pressure is not required and an increase in the water content of the sludge does not occur.

Filed: 1974-03-27
Abstract: Material is pneumatically delivered from above to a sieving surface for seiving, and pneumatic sieve-cleaning in counterflow to the direction of forwarding, as a compressed air blower which periodically sweeps over the underside of the sieve. The frequency and strength of the cleaning air streams are enought, w.r.t. the impinging stream of sieved material, to prevent formation of a deposit of more than single-grain thickness. Preferably, the movement of the cleaing air streams and their frequency are sufficient for this, and transport the coarse material along the sieve.

Title: Short-circuit locator for PCBs with and without components - uses probe to locate local magnetic field increases arising from pulsed supply
Inventor: HOFMANN FRANZ
IPC: G01R31/02
Filed: 1974-09-12
Abstract: The short-circuit locator, for printed circuit boards with and without components, applies a pulsed d.c. voltage to the p.c. board terminals. This pulsed voltage has the same polarity as that for normal operation but is lower in magnitude. A probe scans the components over a coordinate grid and detects local anomalous increases in the magnetic field of the board. This increase is registered acoustically or optically and marks the spot of a short circuit. The pulsed d.c. signal voltage and current are adjustable. The advantage of this method lies in its versatility.

Title: Air turbine for propulsion and power generation - utilises centrifugal force generated by excess pressure of atmospheric air
Inventor: NIEDZOLKA ERICH
IPC: F03G7/10
Filed: 1975-02-10
Abstract: Air compressor takes in air through an entry filter and inlet pipe. It contains reciprocating pistons which deliver air under pressure to small bore tubes. These lead to jets in the side of a cylindrical casing. Within the casing there is a rotor with radial blades mounted on a central shaft. The air escaping from the jets at the ends of the small bore tubes sets the blades and shaft into rotary motion. The shaft projects at both ends through the end pieces of the casing and carries gears at both ends which are used to turn any desired machine. This can be propulsion machinery for land, sea or air vehicles or electrical generating equipment.
